WALL-PAPER-PR INTING MACHINE:

SPECIFICATION forming part of Letters Patent No. 736,043, dated August11, 190%.

Application filed April 1, 1903.

To all whom, it may concern: V

Be it known that I, JAMES A. WATSON, a citizen of the United States ofAmerica, and a resident of Washington, in the District of Oolumbia,haveinvented certain new and useful Improvements in Wall-Paper-PrintingMachines, of which the following is a speci fication.

In printing wall-paper the strip of paper is usually passed first over agrounding-machine, which lays on the ground color, then over a secondprinting-machine, which prints the pattern, and sometimes over a thirdprinting-machine for laying on lines'or other additional patterns forproducing tapestry and other effects. In each printing-machine the paperabsorbs a large amount of moisture, and it is the object of the presentinvention to rapidly dry the paper as it comes from the printing-machinewithout smearing or blurringthe colors, so that the paper may beimmediately taken up by the succeeding machine whether the latter be asecond printing-machine or a mechanism for calendering, embossing, orreeling.-

The invention willbo particularly described in the followingspecification, reference being had to the accompanying drawings, inwhich-- Figure l is a diagrammatic side elevation showing so much of thewallpaper-printing mechanism as is necessary to illustrate the presentinvention; and Fig. 2 is a plan view of the same, parts being brokenaway.

Referring to the drawings, A indicates a primary printing-machine, and Ba secondaryprinting-machine. As illustrated,the primary printing-machineis supplied with asingle-color roll 1 for putting on the ground color onthe otherwise blank paper, and the secondary printing-machine issupplied with a plurality of pattern-rolls 2 for laying on the patternsin various colors. The blank paper is supplied from a roll 3, beingdrawn from the roll bya pair of feed-rolls 4 and'delivered upon aslowly-moving belt 5, which forms a reservoir to contain a quantity ofslack paper. From the belt 5 the paper passes over tension-rolls 6 andthen around the main cylinder ofthe grounding-machine A. After theground color is laid on the paper passes over guide-rolls 7 8 and thensuccessively Serial No. 150,588. (Nb model.)

around heated drying-rolls 9 10 11 12. These drying rolls are soproportioned and arranged that the back of the paper is in contact witheach roll,thus preventing any smear ing of the patterns on the face ofthe paper. I accomplish this by making the first roll 9 of suitablesize, the second 1301110 of less diame ter, the third roll 11 of stillless diameter, dtc. Any desired number of rolls may be arranged in thisway, the smaller rolls being between the larger rolls. The severaldrying-rolls preferably have theiraxes in the same plane, as shown inFig. 1. The dried paper is delivered from the last heating-roll to apoint between the rolls and must be taken out laterally. For thispurpose I use a pair of an= gularly-arranged rolls 13 14. The roll 13guides the paper out from between the dry ing-rolls, and the rollltrestores it to parallelism with the paper running over thedrying-rolls. The roll 14 may be omitted if the machine which operatesnext upon the paper be arranged at right angles to the printing machine.

When the machines are in tandem, the ar rangement shown in Figs. 1 and 2may be used. The paper is drawn from the roll 14: by feedrolls l5 anddelivered upon a slowly-moving belt 16 or other device for accumulatinga quantity of slack paper. From the accumulator 16 the paper passes tothe next machine. As shown, it passes over a second series oftension-rolls 17 and over the multicolor-print ing machine B, whichprints the pattern. A series of drying-rolls, such as those'followingthe primary printing-machine,may be applied to dry the paper as it comesfrom the secondary printing-machine.

It will be evident that drying-rolls arranged as illustrated anddescribed herein may be used with any printingmachine for dryingcontinuous strips of paper or other fabric. I do not, therefore, limitthe presentinvention to the particular combination and arrangement ofelements illustrated. The invention, however, is especially adapted forwall-paperprinting mechanism. In this class of print: ing the paper runsvery rapidly, and it must be rapidly dried in order to save time and 10)floor-space.

Having described my invention, what I claim, and desire to securebyLetters Patent, 15-- 1. In a Wallpaper-printing apparatus, thecombination of a primary printing-machine, aseries of drying-rollsconsecutively decreasing in size, the smaller rolls being locatedbetween the larger rolls, and a secondary printing-machine, the paperpassing successively and continuously over said primary printingmachine,dryingrolls and said secondary printing-machine.

2. In a wall-paper-printing apparatus, the combination of a primaryprinting-machine, a series of drying-rolls consecutively decreas' ing insize, one or more smaller rolls being located between the larger rolls,a diagonallyarranged roll within said series for guiding the paperlaterally and a secondary printingmachiue, the paper passing over saidmachine and rolls in the order stated.

3. In a wallpaper-printing apparatus, the combination of a primaryprinting-machine, aseries of drying-rolls operating in succession uponthe paper as it comes from the primary printing-machine, said rollsbeing so constructed and arranged that the backof the paper travelsoneach roll, an accumulating device or reservoir receiving the paper fromsaid drying-rolls, and a secondary printingmachine receiving the paperfrom said accumulating device or reservoir.

4:. In a Wallpaper-printing apparatus, the combination of a primaryprintingmachine, a series of drying-rolls having their axes in a com monplane,said rolls successively decreasing in size and the smaller rollsbeing located between the larger rolls, a diagonal guideroll between therolls of said series, and a secondary printing-machine, said machinesand rolls operating consecutively upon the paper in the order named.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES A. WATSON.
